Semantic Sensor Network Ontology

Author

W3C Semantic Sensor Network Incubator Group

Description

This ontology describes sensors and observations, and related
concepts. It does not describe domain concepts, time, locations,
etc. these are intended to be included from other ontologies via
OWL imports.

This ontology is developed by the W3C Semantic Sensor Networks
Incubator Group (SSN-XG). The concepts and structure of the
ontology were discussed in the group's meetings and on the mailing
list. For more information on the group's activities see:
http://www.w3.org/2005/Incubator/ssn/

An Observation is a Situation in which a Sensing method has
been used to estimate or calculate a value of a Property of a
FeatureOfInterest. Links to Sensing and Sensor describe what made
the Observation and how; links to Property and Feature detail what
was sensed; the result is the output of a Sensor; other metadata
details times etc.

An observable Quality of an Event or Object. That is, not a
quality of an abstract entity as is also allowed by DUL's Quality,
but rather an aspect of an entity that is intrinsic to and cannot
exist without the entity and is observable by a sensor.

A sensor can do (implements) sensing: that is, a sensor is any
entity that can follow a sensing method and thus observe some
Property of a FeatureOfInterest. Sensors may be physical devices,
computational methods, a laboratory setup with a person following a
method, or any other thing that can follow a Sensing Method to
observe a Property.

An Event in the real world that 'triggers' the sensor. The
properties associated to the stimulus may be different to eventual
observed property. It is the event, not the object that triggers
the sensor.

An Event in the real world that 'triggers' the sensor. The
properties associated to the stimulus may be different to eventual
observed property. It is the event, not the object that triggers
the sensor.

A relation between some aspect of a sensing entity and a
property. For example, from a sensor to the properties it can
observe, or from a deployment to the properties it was installed to
observe. Also from a measurement capability to the property the
capability is described for. (Used in conjunction with
ofFeature).

A relation between the description of an algorithm, procedure
or method and an entity that implements that method in some
executable way. For example, between a scientific measuring method
and a sensor the senses via that method.

A relation between an entity that implements a method in some
executable way and the description of an algorithm, procedure or
method. For example, between a Sensor and the scientific measuring
method that the Sensor uses to observe a Property.

A relation from a Stimulus to the Property that the Stimulus is
serving as a proxy for. For example, the expansion of the
quicksilver is a stimulus that serves as a proxy for temperature,
or an increase or decrease in the spinning of cups on a wind sensor
is serving as a proxy for wind speed.

Relation linking an Observation (i.e., a description of the
context, the Situation, in which the observatioin was made) and a
Result, which contains a value representing the value associated
with the observed Property.

A relation between some aspect of a sensing entity and a
feature. For example, from a sensor to the features it can observe
properties of, or from a deployment to the features it was
installed to observe. Also from a measurement capability to the
feature the capability is described for. (Used in conjunction with
forProperty).

A (measurement) procedure is a detailed description of a
measurement according to one or more measurement principles and to
a given measurement method, based on a measurement model and
including any calculation to obtain a measurement result [VIM

FeatureOfInterest

A feature is an abstraction of real world
phenomena (thing, person, event, etc).

Observation

An Observation is a Situation in which a Sensing
method has been used to estimate or calculate a value of a Property
of a FeatureOfInterest. Links to Sensing and Sensor describe what
made the Observation and how; links to Property and Feature detail
what was sensed; the result is the output of a Sensor; other
metadata details times etc.

skos:closeMatch'observation' [O&M]
Observation in this ontology and O&M are described differently
(O&M records an observation as an act/event), but they record
the same thing and are essentially interchangeable. The difference
is in the ontological structure of the two, not the data or use.
Observation here records a Situation (the estimation of the value
of a Property) and a description of the method that was used (along
with the participants), while O&M interprets an Observation as
the event itself; there must, however, have been an event that lead
to our situation, so both are records of events. The distinction is
between the event itself and the record of what happened in that
event. skos:closeMatch'measurement result' [VIM
2.9] result in VIM is the measured value plus any other
relevant information, which means that measurement result and
observation will often be associated to the same data (a value, a
time, a property, etc.).

Sensor

A sensor can do (implements) sensing: that is, a
sensor is any entity that can follow a sensing method and thus
observe some Property of a FeatureOfInterest. Sensors may be
physical devices, computational methods, a laboratory setup with a
person following a method, or any other thing that can follow a
Sensing Method to observe a Property.

A data sheet records properties of a sensor. A data sheet might
describe for example the accuracy in various conditions, the power
use, the types of connectors that the sensor has, etc. Generally a
sensor's properties are recorded directly (with
hasMeasurementCapability, for example), but the data sheet can be
used for example to record the manufacturers specifications verses
observed capabilites, or if more is known than the manufacturer
specifies, etc. The data sheet is an information object about the
sensor's properties, rather than a direct link to the actual
properties themselves.

Relation between a Sensor and a Property that the sensor can
observe. Note that, given the DUL modelling of Qualities, a sensor
defined with 'observes only Windspeed' technically links the sensor
to particular instances of Windspeed, not to the concept itself -
OWL can't express concept-concept relations, only
individual-individual. The property composition ensures that if an
observation is made of a particular quality then one can infer that
the sensor observes that quality.

Collects together measurement properties (accuracy, range,
precision, etc) and the environmental conditions in which those
properties hold, representing a specification of a sensor's
capability in those conditions. The conditions specified here are
those that affect the measurement properties, while those in
OperatingRange represent the sensor's standard operating
conditions, including conditions that don't affect the
observations.

The set of values that the sensor can return as the result of
an observation under the defined conditions with the defined
measurement properties. (If no conditions are specified or the
conditions do not specify a range for the observed qualities, the
measurement range is to be taken as the condition for the observed
qualities.)

Selectivity is a property of a sensor whereby it provides
observed values for one or more qualities such that the values of
each quality are independent of other qualities in the phenomenon,
body, or substance being investigated.

Section Deploy

Introduction Deploy

The ongoing Process of Entities (for the purposes of this
ontology, mainly sensors) deployed for a particular purpose. For
example, a particular Sensor deployed on a Platform, or a whole
network of Sensors deployed for an observation campaign. The
deployment may have sub processes, such as installation,
maintenance, addition, and decomissioning and removal.

Place to group all the various Processes related to Deployment.
For example, as well as Deplyment, installation, maintenance,
deployment of further sensors and the like would all be classified
under DeploymentRelatedProcess.

Relation between a Platform and a Deployment, recording that
the object was used as a platform for a system/sensor for a
particular deployment: as in this PhysicalObject is acting as a
Platform inDeployment Deployment.

An Entity to which other Entities can be attached - particuarly
Sensors and other Platforms. For example, a post might act as the
Platform, a bouy might act as a Platform, or a fish might act as a
Platform for an attached sensor.

Relation between a System (e.g., a Sensor) and a Platform. The
relation locates the sensor relative to other described entities
entities: i.e., the Sensor s1's location is Platform p1. More
precise locations for sensors in space (relative to other entities,
where attached to another entity, or in 3D space) are made using
DOLCE's Regions (SpaceRegion).

An identifiable characteristic of the environmental and other
conditions in which the sensor is intended to operate. May include
power ranges, power sources, standard configurations, attachments
and the like.

The environmental conditions and characteristics of a
system/sensor's normal operating environment. Can be used to
specify for example the standard environmental conditions in which
the sensor is expected to operate (a Condition with no
OperatingProperty), or how the environmental and other operating
properties relate: i.e., that the maintenance schedule or power
requirements differ according to the conditions.

An identifiable characteristic that represents the extent of
the sensors useful life. Might include for example total battery
life or number of recharges, or, for sensors that are used only a
fixed number of times, the number of observations that can be made
before the sensing capability is depleted.

The conditions a sensor can be exposed to without damage: i.e.,
the sensor continues to operate as defined using
MeasurementCapability. If, however, the SurvivalRange is exceeded,
the sensor is 'damaged' and MeasurementCapability specifications
may no longer hold.

Used to specify ranges for qualities that act as conditions on
a system/sensor's operation. For example, wind speed of 10-60m/s is
expressed as a condition linking a quality, wind speed, a unit of
measurement, metres per second, and a set of values, 10-60, and may
be used as the condition on a MeasurementProperty, for example, to
state that a sensor has a particular accuracy in that
condition.

Describes the prevailing environmental conditions for
MeasurementCapabilites, OperatingConditions and SurvivalRanges.
Used for example to say that a sensor has a particular accuracy in
particular conditions. (see also MeasurementCapability)

Module Data

ObservationValue

The value of the result of an Observation. An
Observation has a result which is the output of some sensor, the
result is an information object that encodes some value for a
Feature.

O&M conflates what we have as SensorOutput and ObservationValue
into observation result, though the OGC standard does say "result
contains a value" and "a result which has a value", which fits
naturally with the model here.
